[1:1 pair matched case-control study on bladder cancer].
A 1:1 pair matched case-control study was conducted in 1988 to investigate the risk factors for bladder cancer. Cases were inpatients suffering from bladder cancer, while controls were those admitted to hospitals not due to urinary diseases and smoking-related diseases such as lung cancer, oral cancer, or throat cancer. A total of 101 pairs of cases and controls from five major hospitals in Wuhan city, matched on sex, age, and hospital, were interviewed regarding their health history, lifestyle, occupational exposures, and familial history of cancer. Bivariate analysis revealed 10 factors significantly associated with bladder cancer. Conditional logistic regression analysis showed that 5 out of the 10 factors were risk factors for bladder cancer. Cigarette smoking, history of urinary diseases, working at the unit with more than one person ever suffering from bladder cancer, and eating mo than 1.5 kilograms of meat monthly were involved highest significant risks, whereas drinking milk appeared to have negative significant association with bladder cancer.
